- B->JpsiX decays
- in
b_to_jpsiX_lines
number of exclusive B->JpsiX lines were usingmake_jpsi/psi2s
instead of_detached_
versions. Why is that? Changing it to_detached_
versions cause cut has ~100% efficiency for signal and reduces rates by 50%
- in
B*ForSpectroscopy
-
B->Dh decays:
-
fix bug in Xib lines in am_min: 5780 -> 5580 MeV
-
tighten cut on dm(Charm) to +-30(25) MeV (for Charm->4h) for B->Charm+hh and B->Charm+hhh decays
-
add cut D_BPVIPCHI2 > 4 for D coming from B->Dh(hh,hhh) decays
-
add cut on average of MINIPCHI2 of D-hadrons > 16/25/36 for D->hh/hhh/hhhh channels
-
add cut on average of MINIPCHI2 of B-hadrons > 16/25/36 for B->Dh/Dhh/Dhhh channels
-
put repeating code in
tight_track
function
-
-
B->JpsiX decays:
- switch to
make_detached_jpsi
as mentioned above - add cut on average{muons}(MINIPCHI2) > 3**2
- add cut on average{Bhadrons}(MINIPCHI2) > (1+n_hadrons)**2
- add Psi2SKp mode to BuForSpectroscopy as it will add another ~3-5% to overall yield, roughly same as D0PiPiPi_K3Pi, for Bd, Lb, Bc such modes are expected to be further suppressed by factor >2x so not that interesting.
- switch to
-
Bc->JpsiPi(3Pi) decays:
- PT(pi)>700 MeV in Bc->JpsiPi (pure guess for now)
- PT(pi_1)+PT(pi_2)+PT(pi_3) > 1500 MeV (pure guess for now)
